NM93C86A Rev. F.1

NM93C86A is a 16,384-bit CMOS non-volatile EEPROM orga-

nized as 1024 x 16-bit array. This device features MICROWIRE

interface which is a 4-wire serial bus with chipselect (CS), clock

(SK), data input (DI) and data output (DO) signals. This interface

is compatible to many of standard Microcontrollers and Micropro-

cessors. This device offers a pin (ORG), using which, the user can

select the format of the data (16-bit or 8-bit). If ORG is tied to GND,

then 8-bit format is selected, while if ORG is tied to V

bit format is selected. There are 7 instructions implemented on the

NM93C86A for various Read, Write, Erase, and Write Enable/

Disable operations. This device is fabricated using Fairchild

Semiconductor floating-gate CMOS process for high reliability,

high endurance and low power consumption.

“LZ” and “L” versions of NM93C86A offer very low standby current

making them suitable for low power applications. This device is

offered in both SO and TSSOP packages for small space consid-

erations.
